Battery has died over the weekend need replacement currently on a Halfords 40 ah battery I would like to replace with a more powerful one.Problem is I’ve never seen a battery like this before it’s got a tube coming out of side all the ones I’ve ever seen are the bog standard ones

Any help would be most grateful
